Dear list,
Sorry about that, my e-mail has been sent too soon by mistake (also from
an incorrect exp. address). I was planning to add further details.
So I'm running Debian Lenny. sessionInfo() gives:
R version 2.7.1 (2008-06-23)
i486-pc-linux-gnu
locale:
C
attached base packages:
[1] stats graphics grDevices utils datasets methods base
Package: SSOAP
Version: 0.5-0
Date: 2009/05/04
Package: XML
Version: 2.3-0
Date: 2009/03/04
Package: RCurl
Version: 0.97-3
Package: XMLSchema
Version: 0.1-0
I must be stupid but I can't find XMLSchema on the omegahat website. (I
just installed the 0.1-0 version a few days ago when trying to use
SSOAP.) Google gives nothing useful for "XMLSchema site:omegahat.org".
http://www.omegahat.org/XMLSchema/XMLSchema_0.1-1.tar.gz
or from a link in
http://www.omegahat.org/XMLSchema/
or via the repository using
install.packages("XMLSchema", repos = "http://www.omegahat.org/R";)
I'm beginner in both web services and R programming (my knowledge is
more in desktop & CORBA Java programming). I am simply trying to make
Java and R communicate (call Java code from R remotely), for use by
someone else who works in R. I'd like to provide him with a fully
functional example. I must recognize that having to step through SSOAP
code to find where the problem lies might be too difficult considering
my current knowledge (knowing I don't intend to become an expert R
programmer). Please don't take it as rude or implying that I'm simply
expecting someone to solve the problem for me: I am ready to investigate
but I'd simply like to have an idea of how difficult it will be. If I
have to patch part of SSOAP or if you think that the functions I need
are not implemented yet, then I'd better not insist and try to
communicate from R to Java using an other way. If on the other hand you
think it should be working and is simply a matter of using the right
version of the right package, or using an other web services platform on
the Java side, or configuring something differently, etc., then I'll
happily dig into it.
Either of Simon Urbanek's rJava or Rserve packages are worth investigating.
More generally, if someone has a suggestion on what to use to call Java
over TCP/IP from R, I'd be interested. I am currently considering OSS as
well as SSOAP. I'd prefer learning an approach that I can reuse for
other languages, so possibly a standard like SOAP or CORBA would be best.
Thanks for any pointer.

D.
I tried different "action" values, because I don't know what I should
put there. But I always get the same error.
Also, FYI, the following command produces the following output:
smg8Def <-
processWSDL("http://smg8.ulb.ac.be:8080/axis2/services/Version?wsdl";,
verbose=TRUE)
processing (sub) schema http://axisversion.sample
1 ) Exception
2 ) Exception
3 ) getVersionResponse
Warning message:
In
processWSDL("http://smg8.ulb.ac.be:8080/axis2/services/Version?wsdl";, :

and then
I also tried a simpler service (WSDL manually created myself, but I
am not sure it is correct although it validates):
smg8EchoDef <-
processWSDL("http://smg8.ulb.ac.be:8080/axis2/services/EchoService?wsdl";,
